## Patch Changes

- b4d53be: feat(core): added Google Tag Manager support
- fix(react): allow `trapFocus={false}` in `CookieBanner`
- fix(nextjs): improved URL validation

## Updated Dependencies

- Updated dependencies [b4d53be]
  - `@c15t/react@1.3.3`

## Usage Notes

- Google Tag Manager (GTM) support is opt-in. Ensure your configuration provides the correct container ID and that GTM events are only dispatched after consent is given.
- Experimental: GTM integration is currently experimental and not recommended for production. See the Next.js guide: [Google Tag Manager](https://c15t.com/docs/frameworks/next/google-tag-manager).
- You can now disable focus trapping in the cookie banner when embedding in modals or constrained layouts:

```tsx
<CookieBanner trapFocus={false} />
```

- Next.js URL validation is stricter. Use a valid URL for any configuration values (e.g., backend URL). Environment variables should contain absolute URLs (https preferred) or valid relative paths depending on your deployment.

```ts
export const c15tConfig = {
  backendURL: process.env.NEXT_PUBLIC_C15T_URL,
};
```

## Technical Details

- Core adds GTM integration hooks that respect consent categories before dispatching events.
- React `CookieBanner` now supports `trapFocus={false}` without side effects on keyboard navigation outside the banner.
- Next.js performs additional checks to prevent malformed URLs from being used at runtime.

## Migration

- No breaking changes.
- If your app relied on loosely formatted URLs, update them to valid absolute/relative URLs to pass the new validation.

## 🧪 Tests

- Added assertions around GTM gating based on consent state.
- Verified focus behavior with `trapFocus={false}` to maintain accessibility expectations.
- Expanded URL validation scenarios for Next.js configuration inputs.
